  Add ignore_submodules to diff options
  
  This adds correct support for an equivalent to --ignore-submodules
  in diff, where an actual ignore value can be passed to diff to
  override the per submodule settings in the configuration.
  
  This required tweaking the constants for ignore values so that
  zero would not be used and could represent an unset option to the
  diff.  This was an opportunity to move the submodule values into
  include/git2/types.h and to rename the poorly named DEFAULT values
  for ignore and update constants to RESET instead.
  
  Now the GIT_DIFF_IGNORE_SUBMODULES flag is exactly the same as
  setting the ignore_submodules option to GIT_SUBMODULE_IGNORE_ALL
  (which is actually a minor change from the old behavior in that
  submodules will now be treated as UNMODIFIED deltas instead of
  being left out totally - if you set GIT_DIFF_INCLUDE_UNMODIFIED).
  
  This includes tests for the various new settings.
